Title: Apparatus for selecting and reading out from information carriers
IPC: G06K21/04
Filed: 1961-08-25
Abstract: 961,568. Statistical apparatus. BOLT BERANEK & NEWMAN Inc. Aug. 25,1961 [Sept. 19, 1960], No. 30809/61. Heading G4M. Apparatus for selecting a card or the like from a stack, and reading information magnetically recorded thereon, comprises a plurality of mechanical releasing members supporting each card of the stack at coded indicia regions, means for selectively operating the releasing members to permit a card with the selected code to separate from the stack, means to cause the card to travel along a predetermined path, and magnetic reading means disposed along the path to read the information from the card. Width-collapsible supporting members 1, 2, 1<SP>1</SP>, 2<SP>1</SP> pass through cut-outs A, B provided at the upper edge of each card, the mouth of each cut-out A being large enough to receive freely a supporting member, whereas cut-outs B have narrower mouths so that the supporting member passing therethrough may be disengaged therefrom only when it is in the collapsed position. Each card is thus supported only by those members passing through cut-outs B on the card, the coding of each card being different from the rest. The collapsing of each supporting member is effected by depressing a corresponding key 1<SP>11</SP>, 2<SP>11</SP>, 1<SP>111</SP>, 2<SP>111</SP>. When, for example keys 2<SP>11</SP>, 2<SP>111</SP> are depressed, members 2, 2<SP>1</SP> are collapsed and only card I-I will fall from the stack. The selected card drops onto a belt 5 at the bottom of a shoot 3 and is moved to the right, during which movement information stored on a plurality of horizontal strips 29 of magnetic tape on the card is scanned and extracted by corresponding reproducing members 29<SP>1</SP>. The card is then automatically returned to the back of the stack. Alternatively, Fig. 3 (not shown), the data on each card may be stored on vertical strips of magnetic tape, and the extraction of the information thereon may be effected by reproducing members while the card is falling within shoot 3.

Title: Improvements in footballs
IPC: A63B41/08
Filed: 1921-11-21
Abstract: 171,707. B³chner, K., and St÷cklein, F. Nov. 20, 1920, [Convention date]. Balls.-Relates to footballs of the kind in which the bladder and valve are inserted through a hole in the outer case and in which the said hole is closed by a piece of flexible material placed over the valve and secured thereto. According to the present invention a flexible disc 4 of sheet steel or similar material is clamped to the bladder by two metal discs 1 and 2. The outer disc 2 has a a central tubular stud 2a which screws into the lower disc 1. A valve is formed by stretching a sheet of rubber between the lugs 1<b> on the disc 1 so as to cover the port 1<a>, thus preventing the air from escaping. Leakage between the discs is minimized by annular grooves 1<c> in the surface of disc 1, and by holes 4b in the flexible disc 4, into which the bladder is pressed. The opening in the cover is filled flush with the outside surface by a dished leather disc 6<a> which is riveted to the disc 4 at one side only, by two rivets 5. The disc 4 together with the valve and bladder may be removed by bending the disc, which has its edges cased in leather or metal to prevent injury to the bladder. A socket connection 8 is fitted for inflating purposes, but during play this is removed and a screw stopper inserted.

Title: Hydraulic system for an industrial truck
IPC: B66F9/22
Filed: 1960-09-09
Abstract: 891,583. Hydraulic apparatus. YALE & TOWNE MANUFACTURING CO. Sept. 9, 1960 [Jan. 28, 1960], No. 31092/60. Class 69 (2). [Also in Group XXX] In a fork lift truck a power steering ram 12 is fed with pressure fluid from an accumulator 13 which is automatically charged to a predetermined pressure each time motor driven pump 14 is operated to move either the fork-lifting ram 10 or the mast-tilting ram 11. In operation, movement of lift ram control valve 18 to the " lift " position operates a switch 20 which energizes a relay 21 having self-holding contacts 21a and contacts 21b over which the pump motor 16 is energized. Fluid is then fed to ram 10 via solenoid valve 19, 19a and control valve 18. Movement of valve 18 to either the " hold " or " lower " position releases switch 20 which thereby opens contacts 20a, but motor 16 continues to be operated until the predetermined pressure is attained in the accumulator, whereupon high pressure switch 22 opens contacts 22a and breaks the self-holding circuit of relay 21. Another pump motor control relay 29 operates similarly to re-charge the accumulator after each actuation of the tilting ram 11. In the event of the pressure in the accumulator falling below a predetermined value, due to non use of the lifting and tilting rams, a low pressure switch 31 closes contacts 31a which energize relay 21 through rectifiers 32, 33, thereby starting motor 16 which continues to run until high pressure switch contacts 22a are opened. Closure of contacts 31a also completes a circuit to a time delay relay 35 which operates an audible or visual warning device 36 if contacts 31a fail to re-open within the delay time of relay 35. In a modification (Fig. 2, not shown), the ram 10 is operated by a push-button switch.

Title: Improvements in or relating to heat meters
IPC: G01K17/16
Filed: 1936-11-18
Abstract: 485,575. Electric signalling systems. JOENS, W. H. Nov. 18, 1936, No. 31617. [Class 40 (i)] For measuring heat used, an induction disc type meter is operated each time a periodically depressed drop loop moves an instrument pointer into contact with a resistance, the pointer being set in accordance with the temperature difference between input and output and the flow. The induction meter is compensated so that it is independent of current variations. The pointer may be made dependent on the temperature difference only. The thermo-couple 1, having junctions in both input and output lines 13, 14 creates an E.M.F. in the resistance 10 which is tapped by contact member 12 positioned by flow-meter 11. With the switch 15 in position 15a this tapped E.M.F. is connected to coil 2 and sets pointer 3. If the switch 15 is making its lower contact 15b the pointer 3 indicates the E.M.F. generated only. The pointer 3 moves over resistance 7 and periodically the drop loop 5 is depressed so that current flows in the coil 16 and induction disc 20 rotates at a speed proportional to the resistance between 7a and moving contact 4. When the loop is raised the disc stops so that the number of rotations of the disc is directly proportional to the heat consumed. The rotations are counted by counter 21 operated through worm gearing. Contacts 25 are closed just after the loop drops and are opened just before the loop rises so that sparking at the resistance is prevented. The meter windings are arranged so that variations in the auxiliary current 9 have no effect on the speed of the disc.

Title: Improvements in or relating to process and apparatus for recovery of ammonia from anammonia containing gas
IPC: C01C1/242
Filed: 1953-11-16
Abstract: Apparatus for absorbing ammonia from coke oven gas in sulphuric acid and crystallizing ammonium sulphate comprises a crystallizer A, an absorber B, a mist precipitator C and a vacuum evaporator D all arranged about a <PICT:0739145/III/1> <PICT:0739145/III/2> common vertical axis.  The absorber which surrounds the crystallizer has a gas inlet 22 and outlet 24 and a ring of spray heads 82 communicating through short pipes 80 with the top of the crystallizer.  From the absorber, gas passes through a riser E and a tangential inlet 30 into the mist separator whence it flows through a central pipe 44 to an outlet 52.  A pump P1 withdraws liquid collecting at the base of the absorber and from the evaporator through a pipe 58, returning it to the crystallizer from beneath and through a perforated deflector 70, whence it rises as a desupersaturated solution to an outlet 62 and thence past a throttling valve 65 to the evaporator.  Supersaturation follows and on return to the crystallizer the current in rising clarifies the crystals, a slurry of the larger sizes being withdrawn through a suction head 76.  Make-up acid is admitted through a pipe 95 into a tar skimmer 94 to which overflow from the absorber is directed through a pipe 90.  Surplus liquid collecting in a tank 86 is drawn on to supply a spray head 106 in riser E. In one modification the absorber is disposed round the lower part of the mist separator and above the crystallizer; in another it extends below and surrounds the base of the crystallizer and the spray heads are downwardly inclined to direct liquid from an annular manifold on to the vessel walls.  In a third embodiment the separator and evaporator are omitted but a centrifugal separator may be inserted in the outlet line.  A further construction provides a trough round the separator outlet 44 with a pipe leading the moisture to the floor whence it drains to the absorber.  Another arrangement locates the separator between the crystallizer situated above it and the absorber which surrounds its lower end.

Abstract: 1494855 Borehole logging TEXACO DEVELOPMENT CORP 31 July 1975 [28 Aug 1974] 31974/75 Heading G1A Well-logging apparatus comprises: a well-logging tool 1 including means 20 receiving unipolar data pulses E 1  representing in number and amplitude a sensed condition, delaying means 33, and means 28 connected to the receiving and delaying means for providing signal pulse pairs E4 each comprising first and second output pulses of opposite polarity, the second pulse starting substantially on completion of the first; a transmission cable; and surface means providing an output signal representing the sensed condition. A photo-multiplier 8 responsive to a short-spaced γ-radiation scintillator 5 provides unipolar energyresponsive data pulses E 1 , and a reference source 12 provides large constant-amplitude pulses E 2  which are mixed with pulses E 1  to form signals E 3 . Pulses E3 are applied to the inputs of a differential amplifier 28 via, respectively a resistor 25 and a delay line 33 (typically of 50 ns), to provide a pair of oppositely-poled pulses in close sequence. This polarity reversal provides a waveform from which D.C. and low-frequency components are absent, and which may therefore be transmitted up a conventional logging cable 51 at a high repetition rate without pile-up. The logging tool may include a duplicate arrangement responsive to a long-spaced detector 5A for providing further output pulses E 4A , which are differentially mixed with the pulses E 4  in an amplifier 45 for feeding to the cable 51. Surface apparatus (Fig. 2 not shown) sorts (68) positive and negative pulses, compensating (85) the heights of data-derived pulses in accordance with the heights of reference-derived pulses, and passing compensated pulses to a processing network (90) connected to a chart recorder (95). The source 12 of reference pulses E 2  may comprise (Fig. 5 not shown) a capacitor (110) alternately charged by a reference voltage source (115) and discharged into a shaping network (122, 123, 125) by the action of a relay (103, 107) driven by an oscillator (100).
